BACKGROUND

1. Field of the Invention

The exemplary invention relates to cover mechanisms used in electronic devices.

2. Description of Related Art

Electronic devices usually have external interfaces for electrically connecting peripheral devices, accessories or networks to the electronic device. Such external interfaces should be protected by the cover mechanisms for continued proper functioning.

Cover mechanisms usually include covers with locks. When the cover mechanisms are used in electronic devices (e.g., mobile phones), the covers are typically locked to the electronic devices by the locking means and, used to cover holes through which the interfaces (e.g., universal serial bus (USB)) of electronic devices are exposed. However, it can be difficult to close off two or more interfaces with one cover mechanism.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring to FIG. 1, an exemplary mobile phone 200 can be seen including an enclosed housing 300, a keypad 17, a display 18, and a cover mechanism 100.

Referring to FIG. 2, the cover mechanism 100 includes a base portion 30, i.e., parts of the housing 300 (e.g. a bottom wall 31 and a sidewall 35), a first cover member 50 and a second cover member 70. The cover mechanism 100 is used to close off three interface holes defined in sidewall 35, which are illustrated and identified as a first interface hole 3512, a second interface hole 3522 and a third interface hole 353. The second interface hole 3522 is positioned between the first interface hole 3512 and the third interface hole 353. A portion of the sidewall 35 between the first interface hole 3512 and the second interface hole 3522 defines a groove 3515 and a slit 3525 therethrough. The groove 3515 and the slit 3525 communicate with the first interface hole 3512 and the second interface hole 3522, respectively. The bottom wall 31 has a locking block 33 protruding therefrom and adjacent to the slit 3525. The locking block 33 is generally rectangular and has a first locking hole 332 aligning with the slit 3525.

Referring to FIG. 3, the sidewall 35 has two latching protrusions 38 protruding from an outside surface thereof. The two latching protrusions 38 are adjacent to the first interface hole 3512 and on the side of the first interface hole 3512 opposite to second interface hole 3522. Each of the latching protrusions 38 is generally L-shaped having a latching end 381 extending therefrom. The latching ends 381 extend in opposite directions.

The first cover member 50 has a first cover portion 51, a latching cutout 52 and a locking protrusion 53. The latching cutout 52 and the locking protrusion 53 are located at opposite ends of the first cover member 50, respectively. The first cover portion 51 is flexible (e.g. flexible rubber) and disposed between the latching cutout 52 and the locking protrusion 53. The first cover portion 51 is configured to cover the first interface 3512 (best shown in FIG. 4).

The latching cutout 52 is configured for receiving and latching the latching protrusions 38 therein. Accordingly, an interior wall of the latching cutout 52 is configured for receiving and latching the two latching ends 381 therein. The locking protrusion 53 is generally L-shaped and includes a first connecting portion 531 and a locking portion 532. The first connecting portion 531 connects the locking portion 532 to the first cover portion 51. The first connecting portion 531 is configured for inserting into the groove 3515. The locking portion 532 defines a second locking hole 535 corresponding to the first locking hole 332.

The second cover member 70 has a second cover portion 71 and a locking pin 75 protruding from a surface of the second cover portion 71. The second cover portion 71 is configured to cover the second interface hole 3522 and the third interface hole 353 (best shown in FIG. 4). The second cover portion 71 is also flexible (e.g. flexible rubber). The locking pin 75 is at one end of the second cover portion 71 and includes a second connecting portion 751, a limiting portion 752 and a pin portion 753. The limiting portion 752 connects the second connecting portion 751 and the pin portion 753.

The second connecting portion 751 connects the limiting portion 752 and the pin portion 753 to the second cover portion 71. The second connecting portion 751 can be received in the slit 3525 when the second cover member 70 engages to the sidewall 35. At this position, the limiting portion 752 is configured for locking with a part of the sidewall 35 between the groove 3515 and the slit 3525 to prevent the second cover member 70 from moving away in a vertical direction (best shown in FIG. 4). The pin portion 753 is configured for locking into the first locking hole 332 and thus prevent second cover member 70 from moving away in a horizontal direction (best shown in FIG. 4). The pin portion 753 has substantially the same size and shape as first locking hole 332.

Referring to FIGS. 4 and 5, the first cover member 50 is locked to the base 30 by latching two latching protrusions 38 into the latching cutout 52. At this time, the locking portion 532 contacts the locking block 33 and located between the locking block 33 and the groove 3515. The second locking hole 535 aligns with the first locking hole 332. Then, the second cover member 70 is locked to the base 30 after the pin portion 753 inserts into the first locking hole 332 and the second locking hole 535. When the latching protrusions 38 are in the latching cutout 52, the first cover member 50 cannot move away from the sidewall 35 in a vertical direction. Also, by a locking of the pin portion 753 into the second locking hole 535, the first cover member 50 cannot move away from the sidewall 35 in a horizontal direction. The vertical movement is stopped by the locking of the limiting portion 752 against the part of the sidewall 35 between the groove 3515 and the slit 3525. The horizontal movement is limited by the locking of the pin portion 753 into the first locking hole 332. The first cover portion 51 closes off the first interface hole 3512, simultaneously, the second cover portion 71 closes off the second and third interface holes 3522 and 353. Therefore, the cover mechanism 100 closes off two or more interface holes, exemplified as the first, second and third interfaces holes 3512, 3522 and 353.

Referring to FIG. 6, when the first interface hole 3512 needs to be exposed, the first cover member 50 will be released from the locked state. During this stage, the first cover member 50 is pulled away enabling the two latching protrusions 38 to disengage from the latching cutout 52. Because the first cover portion 51 is flexible and the pin portion 753 being locked into the second locking hole 535, the first interface hole 3512 can be exposed by bending the first cover portion 51 around the locking portion 532.

When the second and third interface holes 3522 and 353 need to be exposed, the second cover member 70 will be released from the locked state. Because the second cover portion 71 is flexible, the second and third interface holes 3522 and 353 can be exposed by bending the second cover portion 71 around the locking pin 75.
